Rockhounding New Mexico – Sierra County’s Rocks, Minerals & Gems

Sierra County Rock & Gem SocietyRock hunters love New Mexico, and Sierra County is a great example of the reason why. Ancient sea beds erode and reveal fossilized marine life; in some spots, one literally trips over the remains.

Green fluorite is common here, as are many varieties of quartz. Banded agate, a mineral named for its unusual, undulating stripes, is somewhat unique to this area.

According to the head of the Sierra County Rock and Gem Society (SCRAGS), “most rock hunters come to Sierra County to collect carnelian, amethyst, and sulfides.”

Rock hunting tools (and tips) are available at the Rock Shop in Hillsboro.

SCRAGS meets on the first Monday of every month at 6pm at the Geronimo Springs Museum, and coordinates field trips to sites around the county. The first meeting is free to attend.
